' TANNING APPARATUS.

To all whom it may concern Be it known that I, CHARLES J OHN GLASEL, citizen of thejUnited States, and resident of New York city, inv'the county of New York and State of New York, have invented certain new and usefulTanning Apparatus, of which the following isa specification.

, This invention relates totanning, and more especially to a method and? apparatus for depilating, tanning and otherwise treat ing hides or skins in whole orvin part withj circulating fluids containing chemicals, ex tracts, gases or electric current'andxat suitable temperature. 1

T he je of invention'is ,thetreating of the hides and skins-in quantities and arranging them in rows so that when their position is changed they will be found in piles and layers and retaining betweenthem separately a supply of the tanning fluid but so secured that thesaid solution may be drained or shaken out and the hide stretched to exude the same when the container is turned to the properzposition." At the same 1 pelling thefsolution. to

time the weakened tanning extracts which drain into:the lowerend of the container may be replenished with proper chemicals or removed and new liquids substituted and the hides again treated by therotation of the' container andfsubmersion of said hides.

If found desirable a continuous current of the tanning solution ,may be circulated through the containerandabout the. hides and as the container is rotatednthey are stretched and relaxed plopening and .closing their pores to strain the structureof the hide bytheir weight and absorbing and exthoroughly subject thexentire hide to the influence of ,the tanning liquid, or'other treatment administered.

5 When the containerdeavesfits horizontal and submerging position the hidesjare so banked and superimposed-upon each other that their weight immediately tends 1 to squeeze the solution from the lower layers and when theoperation-of soaking the hides is completed, the liquid may be: drawn out of the container and l the, latter, alternately 7 turned from one side to the other'before it is finally set up in its original position toremove the hides after they/separate their vertical arrangement and finally stretch and drain.

continue as long as maybe desired to effect tl efresults as itfis evident that different grades and thicknesses of leather require more or less treatment) The submersion of the'hides or their release from the liquid to stretch anddrain them may also be easily determined. and regulated by the following method and apparatus which is more fully detailed hereinafter, set forth in the claims, and illustrated inthe-aecompanyin'g drawingsWherein- 1 f I. t a 1- ,-Figure 1 is an elevation ofthe apparatus, A .Fig. 2is a vertical sectional view through thesame,.f t

so that after the receptacle has completed a'revolution and theb-ars are at the end of the receptacle,the hidessuddenly drop the limit of the slide 15 and the superfluous tanning solution is shakenlo-os A ;'III the modified form of bar shown in Fig. 8 neither of the bars 12 provided with pins but the hide is clamped between them to avoid injury; A

The receptacle is provided with a partiinternal gear wheel 35 rotated'bythepinioii 36whicl1 is driven by the pulleys 3"! through tion 17 -dividing it into two compartments and each compartment is closed by a water tight door 18 At. one side the receptacle has a pivot 19 journaled in a standard 20 While the other side has a pivot 21 with passages 22 and 23 and surrounded by 2a sleeve 24: secured to the side of the receptacle and carryingthe weight oi the :tank inthe bearing 25.

The passage 23 terminates within the receptacle and carries the tanning extracts to the same vhile thepassage.22-co1n1nunicates with an outlet-"26 that drains the tank through the medium of a pum -'2? and suitable'pipe and liquid is thus circulated through certain ,grooves 29 and- 30 in j the journal box 31 mounted on the stand'32 and carrying the inlet and' outlet connections 33 and3 fl. f e

At the latter-side of the receptacle is fthe The hide carrying bar shownin I ig. 8

i has dowel pins at its ends to {prevent the two parts from sliding past each-other and the two sections are reduced or cut awavto receive the hide and clamp itfso that it'may be hung without injuring it-with perfora tions. I I

When it is desired to operate the 'appa ratus it may "hemmed to a horizontal {P081- tion and the hides strungfon the bars 11 until they completely fill "thefreceptacle or until the desired number are deposited. In

one form' of 'thedevice constructed by me about 150 hides are deposited therein. u A small amount of tanning fluid," f ron175 to 125 gallons for the apparatus just refer-red to as containing 150hides, is then introduced through the opening 33 and passage 23. and the receptacle rotated until the hidesby their movements "thoroughly absorb the liquid or become impregnated with it. When the hide drops by gravity to its -vertical position its: pores are openedand the liquid drains therefrom after being sub;

jected' to the chemicals in the said solution and the pores are again ready to befilled wlth the tanning mixture when submerged in the same at t'hebottom of the tank.

At times the solution may be withdrawn while'the apparatus is in motionand a new and stronger preparation supplied while the rotation proceeds. In the modified construction shown in Figs; 6- and 7 {the tank 40 is mountedon a vertical axis with upper an'dlo'wer' bearings 41 and i2, the latter supporting "the tank, and havlng the inlet 4'3 and-outlet 44:, the

. fornierconnecting with the vertical pipe 45 l having spray ,pipesfl6 at its upper end while the outlet drains into a tank 47' containing the tanning solution. 7 f

A'pump 48 draws the liquid fr m the tank 4.7 through the pipe 49 and forces it up the pipe 45 while the pulleys 50 which operate the pump alsogturn the;pinion gearing with -teeth on the lower side of the receptacle to rotate the same.

V V v :5. In'a "tanning apparatus, the'cdnibinae tion'of a rotatable water tight receptacle, a bar. consisting of a plurality of recessed members andwhose ends are secured in f the sidewalls or "the receptacle, therecessed members "being" so secured to one another brackets attached we the side that ithefre'cesses hconstitute 'an opening adapted to guide-a movablyasupported and suspendedhide hungtherethrough; 7 I 6. In a: tanningjjapparatus,theigcQnibination with a water tight receptacle, 'of'a seetional bar attached at one side thereof and 7 adapted to's'ecureone' edge o'fthe hide, and an apertured guide member fixedly secured to the walls of the receptacle'at a distance from said attached 'bar, the said aperture being adapted to allowltheqhide to freely move and slide therein.

7. Ina tannlng apparatus, the combination of a slidable supporting hide "carrying bar with a fined apertured hide guiding bar spaced apart'there'from. i 8. In a rotatible' tannin -vat, a "block having a stem and a brac et rigidly fat- I tach'ed to a "wall ofthe vat through which said stem is adapted to slide longitudinally, said block being adapted to support one end of a hide carrymg bar. v

9. The herein described process of treating hides which comprises securing one end thereof to a movable member arranged at one side of arotatable receptacle adapted to contain a liquid, rotating the receptacle, and subjecting the hide to recurring sudden shocks by the fall of the said movable member through a limited distance when said member is elevated to its highest position during the rotation of the receptacle.

10. The herein described process of treating hides which consists in securing one end of each of a plurality of hides to separate movable supporting members arranged at one end of a rotatable hide receptacle, supporting the hide at another point between spaced apart guiding members adapted to allow the hide to freely move therebetween, rotating the receptacle, subjecting the hides to the action of suitable media while they are undergoing the various tensions, shocks, pressures, flexures and frictions resultin from said relations.

11. The herein described process of treating hides which consists of repeatedly covering the surfaces of the same with a suitable liquid and alternately freeing their surfaces from the said liquid while suspended in a receptacle, the liquid being circulated over the hides and in and'out of said receptacle until practically exhausted.

12. The process of treating hides which comprises securing them in a rotatable receptacle, rotating the said receptacle and therein subjecting the hides to the action of a suitable medium and also to recurring tensions, shocks, pressures, fleXions and frictions which result from the rotation of the receptacle and their method of being secured therein.

13. The herein described process of treating hides consisting of securing one side of the same in a receptacle by'a crossbar whose ends are adapted to slide to and from the center of the receptacle, filling the latter with a tanning medium to cover the hides, and rotating the receptacle to cause the bar with the hide to shift its osition.

14:. The herein describe process of treating hides for tanning and consisting of immersing the hides in a tanning solution within a vat and securing one edge of each hide in a clamping bar whose ends are adapted to slide lengthwise in the sides of the vat as it revolves, and rotating the vat to cause therrhides to undergo tensions, shocks, pressures, fiexures and frictions.
